Stage 2

There is more to come but we have maxed out the stock air flow meter. I'm happy with the power for now though but in the future I might get an uprated afm

Spec is

DC Sports headers
Tomei test pipes
Ichiba Y-pipe
GReddy Ti-C Exhaust
Cosworth Plenum
HKS Spark plugs
CJM stage 0 RFS
DW 600CC Injectors

Tuned with uprev

 

You will need to ditch the second washer tank for the IC piping Just need to make the drivers side tank return into itself

 

^^^^

roger that houston.

 

What fuel pressure are you guys running..?

 

For those who upgraded the stock 6 injectors rather than going with the injector in plenum route, did you still install the 1 way check valve?

There was only one to install so you should know which one i'm referring to.

 

^^Not sure, I will try to check.

Btw, I've decided to swap out the ATI crank pulley for the stock crank pulley to get my impeller speed down. This is with Sam's recommendation; and the kit was designed to use the stock crank pulley per HKS and GTM; so I think its the best option.

My car goes to the shop on the 26th. Retune is scheduled for the 29th. I am having a new filter, new spark plugs installed, and oil change, in addition to the pulley change. Hopefully the retune will go well and I will get my throttle issues sorted out.

 

I was not aware of that. More info would be great!

 

Thanks Jonny!

Here's a picture for reference on the hose its meant to be installed on. It's the arrow pointing left, near the firewall.

 

I never installed mine I'm using 600cc injectors & return system so I guessed it wasnt needed

 

I believe I do have a check valve in that location, even though I am running 600cc injectors and a fuel return system

 

I have a check valve for the cosworth. I will double check later if theres another one there for the fuel system but im pretty sure there not

 

Hey Ian did some research in the work shop manual (EC32 in the manual index). That looks like a part of the evap emmission system. It captures fuel vapours when the car is not going or when filling up and stores the vapours using charcol. It then purges the vapours into the manifold. So i'm thinking because we are now boosted it may not allow the proper purging thus letting the evap canister to fill. The one way valve will check this. On checking the flow direction on the check valve it confirms my theory.

 

I am currently not running any check valve on my kit.

 

Thanks for your responses guys!!

so Pez, does that mean its a good idea to install the check valve?

 

I would go with it because the evap system is quoting EC32 from the factory service manual.
"The evaporative emission system is used to reduce hydrocarbons emitted into the atmosphere from the fuel system. This reduction of hydrocarbons is accomplished by activated charcoals in the EVAP canister. The fuel vapor in the sealed fuel tank is led into the EVAP canister which contains activated carbon and the vapor is stored there when the engine is not operating or when refueling to the fuel tank.
The vapor in the EVAP canister is purged by the air through the purge line to the intake manifold when the engine is operating. EVAP canister purge volume control solenoid valve is controlled by ECM. When the engine operates, the flow rate of vapor controlled by EVAP canister purge volume control solenoid valve is proportionally regulated as the air flow increases.
EVAP canister purge volume control solenoid valve also shuts off the vapor purge line during decelerating and idling."
Reading the manual the conclusion that i draw is you want the petrol fumes to be purged to inlet manifold and not forced out elsewhere in the evap system. The Q that came to me was what if the petrol fumes were leaked into the engine bay or cabin. HKS would have the definitive answer, thats why they included it. So i'l go with it.

 

Ok cool!

Thanks pezzy!! So the flow goes from EVAP --> Plenum.

I was wondering why the one way valve was pointing towards the plenum, thought it would be the other way round.

 

btw, i was told i need 2mm spacers for the injectors

 

Yep. But check with guys doing your install as well. hope all goes well.

 

I dont believe the OZ cars have the evap canister. I assume u are talking about the item that is located near the rear of the car on the US models.

 

So whats that thing at the back Michael? What's that hose plugged into?
